Vital Sign Set
Measurements of the body’s basic functions. The absence of a pulse, respiration or blood pressure are indications that the patient is dead, hence the term “vital” in the name. Traditionally, there are 4 vital signs: heart rate or pulse, respiration rate, blood pressure and body temperature. Body height and body weight are also often included among vital signs because these measurements are often used (in conjunction with other observations) to provide a gross indication of potential health concerns.
